CONCENTRIC VENT TERMINATION KIT
INSTALLATION INSTRUCTIONS
(Part # KGAVT0601CVT, KGAVT0501CVT)
NOTE: Read this entire instruction manual and refer to the Venting section of the Operation and
Maintenance manual before starting the installation.
This instruction manual covers installation of the 2” and 3” concentric vent termination kit for use on HTP
boilers and water heaters.
The following defined terms are used throughout this manual to bring attention to the presence of
hazards of various risk levels, or to important product information.
DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or serious
injury.
WARNING indicates a potentially hazardous situation which, if not avoided, could result in serious injury
or death.
SAFETY CONSIDERATIONS
Installing and servicing heating equipment can be hazardous due to gas and electrical components. Only
trained service personnel should install or service heating equipment.
This installation shall be done by a qualified service agency in accordance with these instructions, all
applicable codes, and requirements of the authority having jurisdiction. If the information in these
instructions is not followed exactly, property damage, personal injury, or death may result.
Prior to installation, examine all components for possible shipping damage. When working on heating
equipment, observe all precautions in the literature, on tags, and on labels attached to the unit. Follow all
safety codes. Wear safety glasses and work gloves. Have a fire extinguisher available.
Before beginning any installation or modification, be sure the main electrical disconnect switch is in the
“OFF” position. Electrical shock can cause serious personal injury or death.
This vent kit is to be used only for terminating HTP boilers and water heaters. Do not use this kit to
terminate any other appliance. Failure to follow this warning could result in fire, serious personal injury, or
death.

Field supplied pipe and fittings are required to complete the installation. The combustion air and vent pipe
fittings must conform to American National Standards Institute (ANSI) and American Society for Testing
and Materials (ASTM) standards D1785 (schedule-40 PVC), D2665 (PVC-DWV), D2441 (SDR-21 and
SDR 26 PVC), D2661 (ABS DWV), or F628 (schedule-40 ABS). Pipe cement and primer must conform to
ASTM standards D2564 (PVC) or D2235 (ABS).
In Canada, construct all combustion air inlet and exhaust vent pipes for this unit with CSA or ULC certified
schedule-40 PVC, PVC-DWV pipe and pipe cement.
A. ROOF TERMINATION
1. Determine the best location for the termination kit.
NOTE: A roof termination is less susceptible to
damage. It has reduced chances for intake
contaminants and less visible vent vapors.
2. Cut a hole in the roof 4” in diameter for 2”
concentric vent, or 5” in diameter for 3” concentric
vent kit.
3. Partially assemble concentric vent termination kit.
a. Cement Y concentric fitting to larger
diameter kit pipe (see Fig. 1).
b. Cement rain cap to smaller diameter kit
pipe (see Fig. 1).
Do not operate the appliance with rain cap removed. Re-circulation of combustion products may occur.
Water may also collect inside larger combustion air pipe and flow to burner enclosure. Operating
appliance without rain cap could result in product damage, improper operation, personal injury, or death.
4. Install Y concentric fitting and pipe assembly
through the hole in the roof and field supplied
boot/flashing. NOTE: Do not allow insulation or
other material to accumulate inside the pipe
assembly when installing through the hole.
5. Secure assembly to roof structure as shown in
Fig. 4 using field supplied metal strapping or
equivalent support material.
NOTE: Ensure termination height is above the roof
surface or anticipated snow level (1’ in USA or 1 ½’
in Canada) as shown in Fig. 3.
NOTE: If assembly is too short to meet height
requirements, the two pipes supplied in the kit may
be replaced by using same diameter, field supplied
SDR-26 PVC (D2241) pipe. Do not extend
dimension D more than 60” (See Fig. 2.) DO NOT
USE COUPLINGS TO EXTEND PIPE.
NOTE: When shortening the length of the concentric vent, the inner pipe is longer than the outer pipe.
Make sure you cut the same amount from each pipe. DO NOT make the pipes equal in length.

6. Install rain cap and small
diameter pipe assembly in roof
penetration assembly. Ensure
small diameter pipe is cemented
and bottomed in Y concentric
fitting.
7. Cement air inlet and exhaust
vent pipes to concentric vent
termination assembly. See Fig.
4 for proper pipe attachment.
8. Operate boiler through a
heating cycle to ensure air inlet
and exhaust vent pipes are
properly connected to concentric vent
termination connections.
NOTE: Multiple vertical venting is not
allowed.
B. SIDE WALL TERMINATION
1. Determine the best location for the
termination kit.
a. Position termination kit where vent
vapors will not damage plants, shrubs,
air conditioning equipment, or the existing
structure.
b. Position termination kit so it will not be
affected by wind (which may cause recirculation
of combustion products), airborne leaves, light
snow, or fertilizer.
c. Position termination kit where it will not be
subjected to damage from foreign objects, such
as stones, balls, etc.
d. Position termination kit where the vent noise
will not be objectionable to abutters.
2. Cut a hole in the sidewall 4” in diameter for 2”
concentric vent kit, or 5” in diameter for 3” concentric
vent kit.
3. Partially assemble concentric vent termination kit.
a. Cement the Y concentric fitting to larger
diameter kit pipe (see Fig. 1).
b. Cement the rain cap to the smaller diameter
kit pipe (see Fig. 1).
It is very important to properly glue all joints.
Failure to do so can result in property damage,
serious personal injury, or death.

4. Install Y concentric fitting and pipe assembly through the hole.
NOTE: Do not allow insulation or other materials to
accumulate inside pipe assembly when installing
through hole.
5. Install rain cap and small diameter pipe assembly
in Y concentric fitting and large pipe assembly.
Ensure small diameter pipe is bottomed and
cemented in Y concentric fitting.
6. Secure assembly to structure using field supplied
metal strapping or equivalent support material (see
Fig. 6).
NOTE: Ensure termination location clearance
dimensions are as shown in Fig. 5.
NOTE: If assembly needs to be extended to allow
sidewall thickness requirement, the two pipes supplied in the kit may be replaced by using the same
diameter, field supplied SDR-26 (D2241) pipe. Do not extend Dimension D to more than 60” (see Fig. 2).
DO NOT USE COUPLINGS TO EXTEND PIPE.
7. Cement air inlet and exhaust vent pipes to concentric
vent termination assembly. See Fig. 6 for proper pipe
attachment.
8. Operate boiler/heater through a heating cycle to ensure
air inlet and exhaust vent pipes are properly connected to
concentric vent termination connections.
9. Allow 8” center-to-center distance between concentric
vent terminations on multiple boiler installations (see Fig.
7).
